A negatively charged particle called Negatron was discovered. In the Millikan's oil-drop experiment, the charges of the oil-drops in five experimetns are reported as 3.2xx10^(-19) coulomb, 4.8xx10^(-19) coulomb, 6.4xx10^(-19) coulomb 8xx10^(-19) coulomb and 9.6xx10^(-19) coulomb. Calculate the charge on the negatron.
